Develop design criteria, mass balances, process calculations, hydraulic assessments, and equipment sizing to support informed technical and investment decisions.
Design biological, physical and chemical, nutrient-removal, tertiary-treatment, and solids-processing systems that respond to clients’ operational and regulatory needs.
Apply and review process models using tools such as GPS-X, BioWin, SUMO, and Visual Hydraulics to assess alternatives, troubleshoot complex issues, and optimize treatment performance.
Review process flow diagrams, P&IDs, calculations, specifications, equipment selections, and technical reports to uphold quality and consistency across project deliverables.
Lead technical workshops and clearly communicate recommendations to clients, operators, vendors, and multidisciplinary design teams.
Guide permitting, contract administration, commissioning, and construction-support activities throughout the project lifecycle.
Strengthen our technical community by providing QA/QC, mentoring junior and intermediate engineers, leading proposals, and supporting trusted client relationships.

The Skills That Set You Apart

At least 10 years of progressive water or wastewater process engineering experience, including conventional and advanced treatment processes.
A Professional Engineer designation and the ability to apply sound engineering judgment to complex technical assignments.
Demonstrated experience in process design, modelling, optimization, equipment evaluation, and equipment selection.
Strong knowledge of process controls, instrumentation, plant operations, commissioning, permitting, contract administration, and construction-support services.
Proven ability to independently lead technical work, complex proposals, and multidisciplinary project teams in a consulting environment.
Strong technical writing, presentation, client communication, proposal-development, and problem-solving skills.
A valid driver’s licence and willingness to travel periodically to client sites and project locations.
